May 2025: Delivered a new Skill Builder Problems section within the Derivative Rules documentation for mphowardlab/essential-math. The section includes five practice problems with detailed solutions, covering differentiation techniques (product rule, chain rule, and trigonometric derivatives). This work enhances self-guided learning and reinforces core calculus concepts. No major bug fixes were recorded this month.

April 2025: Delivered practical integrating-factor examples for first-order ODEs in mphowardlab/essential-math, including a mole balance in a tank with varying flow rates and a hormone-level model. Updated credits to attribute the author, and ensured runnable teaching materials with clear documentation to facilitate student learning and quick course adoption.
